RAZOR-STROPPER.

To all whom it may concern:l

Be it known that I, ALLrsoN'I-I. FLEMING, a citizen of the UnitedStates, residing at Fairmont, in the county of Marion and State of WestVirginia, have invented a new and useful Razor-Stropper, of which thefollowing is a specification.

This invention relates to razor stroppers, and has for its principalobject to provide a tool of very simple construction, and which may beemployed for holding and stropping the blades of practically any form oisafety razor now onithe market.

A further object of the invention is to provide a stropper in which thepressure exerted on the blade may be increased or decreased by theoperator during the stropping operation without change in the mechanism.

A still further object of the invention is to provide a device oi thisclass in which the blade holder is pivotally mounted and is directlyconnected to the handle of the device, so that it may be turned by handat the end of each stroke without depending on` friction between thestropper and strap for accomplishing this result.

A still further object of the invention is to provide a blade holderwhich is directly under the control of the hand, and which is turnedback and forth by a natural movement of the hand at the end of eachstroke.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size and minor details'of the structure may be made without 'departing from the spirit or sacrificing any of the advantages oithe invention.

In the accompanying drawingszMFigure l is a per spective view of a razorstropper constructed in accordance with the invention, Fig. 2 is alongitudinal sectional elevation of the same drawn to an enlarged scale.Fig. 3 is a transverse sectional view showing the position of the partswhen making a stroke in one direction. Fig. 4 is a similar view whenmaking a stroke in the opposite direction. Fig. 5 is a detailperspective view, partly in section of the auxiliary blade removed.

Similar numerals of reference are employed to indicate correspondingparts throughout the several rig ures of the drawings.

To the carrying and operating handle l0 is secured a strip of metal bentinto the form of an angle bar ll, the two webs oi which are arranged atan acute angle to each other, and these webs are rigidly connected neartheir opposite ends by V-shaped filling blocks l2. The

Specification of Letters Patent.

Application filed June 14,

blocks l2 form bearings for the reception of a rock shaft l5, thereduced end portions of which pass through openings in the blocks, whilethe major portion of the length of the shaft is of rectangular iorm incross section and carries a pair of spring jaws 16 which serve as aholder for any of the single edge razor blades, such, for instance, asthe blades used in the Star safety razor. Near the opposite ends of theshaft are small pinions 18 that intermesh with arcuate racks 19.

Pivoted to the angle bar ll is a second angle bar 2O oi approximatelythe same length as the angle bar ll, and the two webs oi which arearranged at an obtuse angle to each otheraliording suiiicient room forthe smaller angle bar ll to play back and forth, as shown in Figs` 3 and4, without coming into contact therewith during the stropping operation.In pivoting the parts together, the angle bar 20 is provided with a pairoi lugs 2l which project upward through openings in the angle of bar ll,and a pivot pin 22 is introduced through openings formed in these lugs,the pin fitting at the juncture of the two webs of the angle bar Il, asuitable opening 23 being formed in one oi the blocks l2 to permit theconvenient introduction of the pin.

The two racks 19 are approximately in the form of quadrants, and theirends are pivotally secured to the webs of the angle bar 20, the racksbeing curved on lines struck from the center 0i the pivot pins 22, sothat the pinions 18 may freely mesh therewith without danger of binding.

In order to permit the stropping oi two edged blades, such, forinstance, as those employed in the Gillette type, a secondary holder 25is employed, this holder having pins on one jaw arranged to pass throughthe openings in the blade, and, also, to fit in openings ou the placedin position in the main holder I6.

The angle bar 20 is maintained in contact with the strap, and at the endof each stroke the handle l0 is turned for the purpose of carrying overthe angle bar ll and with it the shaft l5. During this movement the webof the angle bar 20 which was free during the rst and the holder as awhole is swung with the shaft as a center owing to the connectionbetween the pinions and the racks, and the edge of the blade is forceddown into Contact with the surface oi the strap. The edge of the bladecornes into contact with the edge oi the strap before the angle bar 1Ican engage with the angle bar 20, so that the operator is free to exertany desired pressure on the blade during the stropping operation and thestropping may be as light or heavy as the condition of the blade mayrequire.

I claim l. In a razor stropper, a bar or support having' a pair ofangularly related webs arranged for alternate contact stroke is movedover into engagement with the strap,

with the strap, and a pivotally mounted manually operable blade carrierarranged in said support.

2. In a razor stropper, a bar or strip having angularly related strapengaging surfaces, a pivotally mounted blade carrier supported thereby,and an operating handle connected to the blade carrier and through whichpressure may be exerted on the carrier and blade.

3. In a razor stropper, a strap engaging supporting member havingangular-ly related faces for Contact with the strap, a blade carrier,and an operating handle indirectly connected to said member and to thecarrier.

4. In a razor stropper, a strap engaging bar having a pair ot' angularlyrelated surfaces arranged to be brought alternately into contact withthe strap, a pivotally mounted blade carrier, and an operating memberforming a support for the pivoted carrier and through which pressure maybe exerted on the carrier and blade.

5. In a razor stropper, a pivotally mounted operating member, a strapengaging member pivoted thereto, said strap engaging member having apair of angularly related surfaces for alternate contact with the strap,a blade carrier pivotally mounted in the operating member, and a gearingconnection between the blade carrier and the strap engaging member.

(i. In a razor stropper, an operating member, a strap engaging memberpivoted thereto, said strap engaging member having a pair of angularlyrelated surfaces for alternate contact with the strap, a rock shaftmounted in the operating member, a gearing connection between the rockshaft and the strap engaging member, and a blade carrier on said rockshaft.

T. In a razor stropper, an operating member, a rock shaft journaledtherein, a blade carrier on the rock shaft, a pinion secured to the rockshaft, a strap engaging member pivoted to the operating member, saidstrap engaging member having a pair of angularly related surfaces foralternate contact with the strap, and a rack carried by said strapengaging member and intermeshng with said pinion.

8. In a stropper, a handled operating member including an angle barhaving a pair of webs at an acute angle to each other, a strap engagingbar having a pair of Webs at an obtuse angle to each other, the twomembers being pivotally connected together, a pair of racks carried bythe strap engaging member and extending through openings formed in theoperating member, a rock shaft journaled inthe operating member, a pairof pinions on said rock shaft and intermeshing with the racks, and ablade carrier secured to said rock shaft.

9. In apparatus of the class described, a strap engaging bar comprisinga pair of webs arranged. at an obtuse angle to each other, said barhaving a pair of spaced upwardly extending lugs, a second angle barhaving a pair of Webs arranged at an acute angle to each other andprovided with openings for the passage of the lugs, a pivot pinextending through openings in said lugs and forming a pivotal connectionbetween the two bars, angular blocks arranged at the ends of theoperating member, a rock shaft journaled in said blocks, pinions on therock shaft, a pair of racks carried by the strap engaging bar andintermeshing with the racks, and a blade carrier on said rock shaft.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
